Abstract

607,670. Locking rods. DOWTY EQUIPMENT, Ltd., and SNELL, M. S. March 11, 1946, No. 7587. [Class 80 (iii)] [Also in Group XXXVII] A number of push-buttons 7a ... 7d have rollers 8 which engage slidable stop-members 9a ... 9c so that only one button can be depressed at a time, a depressed button being raised to its normal out position by the depression of any other button. The members 9a ... 9c may have humps, Fig. 3 (not shown), to give a snap-action. The buttons may operate fluid valves, an electric switch (see Group XXXVII) and stop a drum or other rotating member at predetermined points.
